Fedora 35 is:
- `ansible_os_family = 'RedHat'`
- `ansible_distribution_major_version = '35'`
Our RedHat checks against v7/v8 are really for RHEL derivatives (CentOS, Rockylinux,
AlmaLinux), but the same checks (by coincidence) apply for Fedora 35.
The problem is that `'35' > '7'` (comparing these as strings) is
`false`.
This patch makes sure that we always cast
`ansible_distribution_major_version` to an integer.
